An oil field was set on fire after a drone strike in Iraq's Dohuk province, in the Kurdish region. The incident on Tuesday is the latest in a series of attacks on oil facilities in northern Iraq.

A drone attack halted production at the Sarsang oilfield in Iraq’s Kurdistan region on Tuesday only hours before its U.S. operator signed a deal to develop another field.

No group has claimed responsibility, but the attacks have heightened tensions between Baghdad and Kurdish authorities, raising concerns about the region’s energy security.
